The US missile defense system is no match for the new intercontinental ballistic missile (ICBM) that Russia tested this week, a senior Russian official said Friday.

Deputy Prime Minister Dmitry Rogozin, who oversees the defense industry, hailed Thursday’s tests as a success and dubbed the new ICBM a “missile defense killer.”

“Neither current nor future American missile defense systems will be able to prevent that missile from hitting a target dead on,” he said, during an event organized by the ruling United Russia party.

The Russian Defense Ministry was more modest in its appraisal of the test, carried out by the Strategic Missile Forces at the Kapustin Yar testing site, between Volgograd and Astrakhan, on Thursday.

“The test launch was a success as the [simulated] warhead hit a designated target within the set time frame,” said a Defense Ministry statement issued Thursday.

The US missile defense system in Europe, which NATO and the US say is aimed at countering threats from North Korea and Iran, has been a particular source of friction in US-Russian relations for a number of years.

Russia and NATO formally agreed to cooperate over the European missile defense system at the 2010 NATO summit in Lisbon, but talks foundered, in part over Russian demands for legal guarantees that the system would not target its strategic nuclear deterrent.

In mid-March, the US announced that it was modifying its planned missile defense deployment to Poland, dropping plans to station SM-3 IIB interceptors in the country by 2022.
